Answer:
260
Step-by-step explanation:
When x represents whole numbers less than 200, the function
f(x) = 2x - 20 .......... (1)
represents the profit earned from selling x carnations for a school fund-raiser.
Therefore, the profit earned from selling 140 carnations for the school fund-raiser will be given by the equation (1) as
f(140) = 2(140) - 20 = 280 - 20 = 260.
Therefore, 260 is the value of f(140). (Answer)
If you have 1 nickle, how many quarters do you have? (3)
If you have 4 nickles, you have 3 times as many quarters (3)(4) = 12
If you have n nickles, then you have 3n quarters so 3n = q, you have a slightly different equation.
If you fix this equation and use substitution like you did, you can get the right answer; you can also try to work in the other information that you have - converting all coin values to cents
5n + 10d + 25q = 460
Start here: A = 18 ft^2 = L * W. Next, L = 2W.
Merging these 2 formulas lets us eliminate L:
18 ft^2 = (2W) * (W) = 2W^2.
So W^2 = 9 ft^2, and W=3 ft. Please use L = 2W (from above) to calculate L.

Step-by-step explanation:
In propositional logic and Boolean algebra, De Morgan's laws are a pair of transformation rules that are both valid rules of inference. ... The rules allow the expression of conjunctions and disjunctions purely in terms of each other via negation.
